OHCC determined that the best approach would be to buy a drone and use it to survey each of its mining operations on a regular basis. After doing its research, the company chose a Kespry Drone 2s System. The Kespry Drone 2s As simple to use as it is reliable and accurate, the Kespry Drone 2s is lightweight, durable and one of the most advanced autonomous aerial data collection tools in the world, accord- ing to the company. The Kespry Aerial Intelligence Platform delivers end-to-end performance in a single, seamlessly inte- grated system. The lightweight quadcopter design maximizes airtime and area covered. The system ensures uninterrupted flight and immediate data transfer, even in more remote areas. The Kespry Drone 2s includes a high-quality dual frequency GNSS receiver designed to eliminate multipath errors and mitigate electronic interferences common in industrial set- tings. Using PPK (Post Processed Kinematic), the system automatically processes field data at a new level of repeatable accuracy that serves a wide range of valuable professional applications, including topographic maps for design. Designed to make field data capture quick and simple, there are no joysticks. You create a mission with the supplied iPad and the touch of your finger. The Kespry Drone 2s calculates the flight path and flies autonomously, using a LiDAR sensor to avoid obstacles. The Kespry system manages the transfer and processing of data within the platform. No piloting, SD cards or clumsy integrations for you to manage. Just high-resolution orthoimagery available in the Kespry Cloud in minutes. Built for industrial uses, the Sony UMC-R10C camera has a large Exmor APS-C Sensor that captures 20 megapixels of color detail to accurately calculate volumes, precisely mea- sure distance and angles, and safely identify hazards or damage. Kespry configures each camera to maximize image quality for specific job types. Geotagged high-resolution images are processed using photogrammetry in the Kespry cloud. A single orthomosaic image is created to deliver high quality topographic maps, dimensional and volumetric data, and rich business insights. Other Benefits OHCC not only uses the Kespry drone for site surveys and future planning, it is also used to create materials for permit applications and calculate reserves. "Our drone helps us create real-time data for our mines," Gavin said. Two additional benefits of using a drone concern safety and accuracy. "No one has to walk through the brush to get to the back of the mine site now, or walk along a high-wall, which can sometime be dangerous," Gavin said. "Our mine sites are sometimes 60 to 80 ft. deep. With the drone, I can go to one of our sites and set it up, and survey the entire operation from where I am standing." OHCC dug deep before choosing Kespry as its drone provider. "We shopped around a lot and we talked to a lot of different people," Gavin said. "One of the big things with Kespry is the ground control, the ease of setting up a base station. The features
